A kind of manufacturing method of steam heating pot

Abstract

A steam heating pot comprises a pot body which comprises an inner shell and an outer shell, and a gap reserved between the inner shell and the outer shell serves as a vaporization cavity under negative pressure. The vaporization cavity is filled with 1-50g of water, the internal pressure value of the vaporization cavity is -1-20 millimeters of water, and each of the inner shell and the outer shell is 0.4-1mm in thickness. Condensate water is prestored in the vaporization cavity between the inner shell and the outer shell, after side seams of the inner shell and the outer shell are welded, a steam inlet and a steam outlet are 4-6mm in inner diameter and reserved at the edges of the inner shell and the outer shell, saturated steam at the temperature of 250-400 DEG C is fed into the vaporization cavity through the steam inlet, and when the temperature of the steam at the steam outlet approaches to that of the steam at the steam inlet (inexistence of condensate water in the vaporization cavity needs to be guaranteed), the steam inlet and the steam outlet are quickly sealed, and the steam inlet and the steam outlet are connectedly hermetically welded to the weld seams at the edges of the inner shell and the outer shell.

Description

technical field [0001] The invention relates to a heating device and a manufacturing method thereof, in particular to a steam heating pot and a manufacturing method thereof. Background technique [0002] In daily life, there are many types of pots that people use, including vegetable pots, soup pots, etc. During use, sometimes due to negligence or excessive fire, the pot is heated at a relatively high temperature, so that the food becomes paste, affecting people's consumption, and even causing waste. In order to prevent the food from becoming mushy after being heated, some pots with composite bottoms have appeared on the market, and some pots have additional non-stick coatings, which are unsafe for eating. [0003] In addition, in the production process of some products, various heating devices and various pots are used to heat certain substances. If the operation is not done properly, overheating will also occur, which will affect the normal production. Contents of the i...
